Impressed current device responsive to the operative parameters of the structure to be protected

摘要

It is described a method for impressed current cathodic protection against corrosion of water heater tanks (1), in particular accumulator tanks. According to this invention said impressed current is regulated according to one or more operative parameters variable in time, at least one of said operative parameters being identified directly during the function of said water heater (1) or derived indirectly from one or more further operative parameters, in turn at least one of said further operative parameters being identified directly during the function of said water heater. The means adapted to permit the application of said method are also described herein. <IMAGE>
